Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534908, here are decompositions:

29 + 31534879 = 31534908
37 + 31534871 = 31534908
89 + 31534819 = 31534908
107 + 31534801 = 31534908
109 + 31534799 = 31534908
151 + 31534757 = 31534908
157 + 31534751 = 31534908
179 + 31534729 = 31534908

Showing the first eight; more decompositions exist.
